Description

Technical Field

[0001] This utility model belongs to the field of headwear technology, specifically relating to a shark clip. Background Technology

[0002] Hair clips, as common head ornaments, are highly favored by women. The shark clip, using its comb-like teeth to secure hair, is one of the most common hair clips for achieving an upward bun, allowing all hair to be above the neck. While there are many styles of shark clips available, they all require the hair to be pre-bent by hand before using the clip to secure it, which is limiting in use. Pre-bent hair often results in tangles. Furthermore, most existing shark clips have design or structural flaws, affecting driving or preventing the user from lying back, posing safety hazards. In addition, there are numerous cases each year of injuries caused by falls or using shark clips while driving. More seriously, in 2024, a fall resulted in a shark clip piercing the back of the head, causing a skull fracture and leaving the person in a vegetative state. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a shark clip that solves the problems of poor safety performance, inconvenience of use, and easy detection of tangled hair in existing shark clips.

[0004] To achieve the above-mentioned technical effects, the technical solution adopted by this utility model is as follows:

[0005] A shark clip includes a first clip body, a second clip body, and a pivot assembly. The first clip body and the second clip body are rotatably connected by the pivot assembly. The first clip body has a first clamping plate and a first pivot plate connected to the left end of the first clamping plate. The second clip body has a second clamping plate and a second pivot plate connected to the left end of the second clamping plate. The first and second clamping plates are arc-shaped plates of the same size, with an arc similar to the curvature of the back of the human head. The second clamping plate is located directly above the first clamping plate and is parallel to it. The second pivot plate is the same shape and size as the first pivot plate, both having a V-shaped structure and being symmetrical about the horizontal plane. The ends of the first and second pivot plates are open. The pivot assembly is connected to the V-shaped bottom of the first and second pivot plates that are close to each other. The lower surface of the second clamping plate has several vertical clamping teeth.

[0006] Furthermore, the left and right end plates of the second pivot plate are both flat plate structures, and the right end plate of the second pivot plate is arranged along the tangent direction of the left end of the second clamping plate.

[0007] Furthermore, the left end plate of the second pivot plate adopts a flat plate structure, and the right end plate connected to it has an arc-shaped structure. The second pivot plate is connected to the second clamping plate through the right end plate, and the right end plate of the second pivot plate is an extension of the second clamping plate on the left end face.

[0008] Furthermore, the left end plate of the second pivot plate adopts a flat plate structure, and the right end plate connected to it has an arc-shaped structure. The second pivot plate is connected to the second clamping plate through the right end plate. The arc center of the arc end of the second pivot plate is located on the lower edge of the left end face of the first clamping plate, and its arc center angle α is 50-60°. The left end plate of the second pivot plate is set along the normal of its arc end.

[0009] Furthermore, the first pivot plate and the second pivot plate have a flat portion formed on the surface wall adjacent to each other at their V-shaped bottoms, and the pivot assembly is located at the flat portion.

[0026] A type of shark clip, such as Figure 1-3As shown, the shark clip includes a first clip body 1, a second clip body 2, and a pivot assembly 3; the first clip body 1 and the second clip body 2 are rotatably connected by the pivot assembly 3. The first clip body 1 has an integrally formed first clip plate 11 and a first pivot plate 12, with the first pivot plate 12 connected to the left end of the first clip plate 11. The second clip body 2 has an integrally formed second clip plate 21, a second pivot plate 22, and several vertical clamping teeth 23. The second pivot plate 22 is connected to the left end of the second clip plate 21, and the vertical clamping teeth 23 are connected to the lower surface of the second clip plate 21. The several vertical clamping teeth 23 are arranged in 2-3 rows at equal intervals on the lower surface of the second clip plate 21. The first clip plate 11 and the second clip plate 21 are arc-shaped plates of the same size, and both have an arc similar to the curvature of the back of the human head. The second clip plate 21 is located directly above the first clip plate 11, and the two are parallel to each other. The second pivot plate 22 and the first pivot plate 12 are the same in shape and size, both having a V-shaped structure and being symmetrical about the horizontal plane. The two ends of the first pivot plate 12 and the second pivot plate 22 are open. A flat portion 13 is formed on the adjacent surface wall of the bottom of the first pivot plate 12 and the second pivot plate 22. The pivot assembly 3 is located between the two flat portions 13 and connects the first pivot plate 12 and the second pivot plate 22.

[0027] In this embodiment, the left end plate 221 and right end plate 222 of the V-shaped structure constituting the first pivot plate 12 and the second pivot plate 22 can both be flat plate structures, such as... Figure 2 As shown, at this time, the right end plate 222 of the second pivot plate 22 is arranged along the tangent direction of the left end of the second clamping plate 21. Of course, the left end plate 221 and the right end plate 222 constituting the V-shaped structure of the first pivot plate 12 and the second pivot plate 22 do not have to be entirely flat structures. For example, the left end plate 221 of the second pivot plate 22 can be flat, and the right end plate 222 connected to it can be arc-shaped. The second pivot plate 22 is connected to the second clamping plate 21 through the right end plate 222, and the right end plate 222 of the second pivot plate 22 is an extension of the second clamping plate 21 on the left end face. Preferably, in order to accommodate more hair, the left end plate 221 of the second pivot plate 22 can be flat, and the right end plate 222 connected to it can be arc-shaped, and the arc-shaped surface extending from the second clamping plate 21 is more upwardly convex. Figure 3 As shown, the center of the arc at the curved end of the second pivot plate 22 can be located on the lower edge of the left end face of the first clamping plate 11, with a center angle α of 50-60°. The left end plate 221 of the second pivot plate 22 is set along the normal of its curved end. To facilitate better gripping of the shark clip by the user, anti-slip textures (not shown in the figure) are provided on the opposing surfaces of the left end plates 221 of the first pivot plate 12 and the second pivot plate 22. In addition, in this embodiment, the corners of the first clamping body 1 and the second clamping body 2, as well as the joints of various parts where there are sharp edges, are all smoothly transitioned by rounding.

[0028] The pivot assembly 3 is used to keep the second clamping plate 21 pressed against the first clamping plate 11 under the absence of external force, so that the second clamping plate 21 and the first clamping plate 11 are always in a closed state. The pivot assembly 3 is an elastic component, such as a torsion spring and a rotating shaft passing through the torsion spring. The two ends of the rotating shaft are fixed by limiting pieces (not shown in the figure) on the first pivot plate 12 and the second pivot plate 22. It can also be a C-shaped spring assembly. In the field of hairpins, the pivot assembly 3 is a common rotating connection component, and it will not be described in detail in this embodiment.

[0029] This invention designs and processes the first and second clamps into arc-shaped plates that conform to the curvature of the back of the human head. Two pivot plates, which allow the user to grip and open the first and second clamps, are connected to one end of the two clamps. When in use, the first clamp is placed against the back of the head, so that the invention does not affect the user's ability to lie back, making it convenient for driving or resting. At the same time, since the clamping teeth are located on the lower surface of the second clamp and above the first clamp, they are not exposed, thus avoiding the safety risks such as accidental injury caused by exposed clamping teeth. Example 2

[0030] like Figure 4 , 5 As shown, this embodiment of the shark clip is based on Embodiment 1, with a third clip 4 added above the second clip 2 of Embodiment 1, and rotatably connected to the right end of the second clip 2 via a pivot assembly 3. Specifically, the third clip 4 has a third clip plate 41 and a third pivot plate 42 connected to the right end of the third clip plate 41. The lower surface of the third clip plate 41 also has several vertical clamping teeth. The combined structure of the third clip plate 41 and the third pivot plate 42 is exactly the same as the combined structure of the second clip plate 21 and the second pivot plate 22. The right end of the second clip plate 21 is connected to a fourth pivot plate 24, which has the same structure as the first pivot plate 12. The third clip 4 is rotatably connected via the pivot assembly 3 located between the third pivot plate 42 and the right pivot plate.

[0031] This invention features a multi-layered clamp design, which provides better fixation and ease of use when hair is coiled up, while also avoiding the risk of hair tangling caused by the pre-coiling method using common shark clips.

[0032] This utility model is not limited to the specific embodiments described above. For those skilled in the art, all modifications made based on the above concept without creative effort fall within the protection scope of this utility model.
